The Best Way to Read a Hydraulic Schematic Mentored Engineer

In every hydraulic system, you will have one function that requires full flow and another that needs much less flow. This is where flow reducers come in. The most basic type is an orifice which is a hole drilled in what would otherwise be a plug. As you can imagine, there is a fixed amount of oil that can be pushed through the hole.

The ash then settles to the bottom of the conveyor, and is efficiently conveyed to an inclined section of the system for dewatering, producing a manageable product. At the top of the incline, a discharge chute directs the ash into a storage bin or truck. The Allen-Sherman-Hoff SCC system is also ideal for handling mill rejects and economizer ash.
